Features:
Due to the characteristics of the two-phase structure, through the correct control of the chemical composition and heat treatment process, DSS has the advantages of ferritic stainless steel and austenitic stainless steel.
Compared with austenitic stainless steel, the advantages of duplex stainless steel
(1) The yield strength is more than double that of ordinary austenitic stainless steel, and it has sufficient plastic toughness for forming. The wall thickness of the storage tank or pressure vessel made of duplex stainless steel is 30-50% less than that of commonly used austenite, which is beneficial to reduce costs.
(2) It has excellent resistance to stress corrosion cracking. Even the duplex stainless steel with the lowest alloy content has higher stress corrosion cracking resistance than austenitic stainless steel, especially in the environment containing chloride ions. Stress corrosion is a prominent problem that ordinary austenitic stainless steel is difficult to solve.
(3) The corrosion resistance of 2205 duplex stainless steel, which is the most common application in many media, is better than that of ordinary 316L austenitic stainless steel, while super duplex stainless steel has extremely high corrosion resistance. In some media, such as acetic acid, Formic acid can even replace high-alloy austenitic stainless steel and even corrosion-resistant alloys.
(4) It has good local corrosion resistance. Compared with austenitic stainless steel with equivalent alloy content, its wear resistance and fatigue corrosion resistance are superior to austenitic stainless steel.
(5) The coefficient of linear expansion is lower than that of austenitic stainless steel, close to carbon steel, suitable for connection with carbon steel, and has important engineering significance, such as the production of composite panels or lining.
(6) No matter under dynamic load or static load conditions, it has higher energy absorption capacity than austenitic stainless steel. This has obvious advantages for structural parts to deal with unexpected accidents such as collisions and explosions. Duplex stainless steel has practical application value. .
The weakness of duplex stainless steel compared to austenitic stainless steel
(1) The universality and versatility of the application are not as good as austenitic stainless steel, for example, its use temperature must be controlled below 250 ºC.
(2) Its plastic toughness is lower than that of austenitic stainless steel, and its cold and hot processing technology and forming performance are not as good as austenitic stainless steel.
(3) There is a middle temperature brittle zone, and the process system of heat treatment and welding needs to be strictly controlled to avoid the appearance of harmful phases and damage performance.
Compared with ferritic stainless steel, the advantages of duplex stainless steel
(1) The overall mechanical properties are better than ferritic stainless steels, especially the plastic toughness, which is not as sensitive to brittleness as ferritic stainless steels.
(2) In addition to stress corrosion resistance, other local corrosion resistance is better than ferritic stainless steel.
(3) The cold working process performance and cold forming performance are far superior to ferritic stainless steel.
(4) Welding performance is also far superior to ferritic stainless steel. Generally, preheating is not required before welding, and no heat treatment is required after welding.
(5) The application range is wider than ferritic stainless steel.
The weakness of duplex stainless steel compared to ferritic stainless steel
The alloy element content is high, the price is relatively high, the general ferrite does not contain nickel.
